What is the torque setting for the front and rear subframe to chassis nuts and bolts? Thanks, Jim Ken Wilkinson Member Car #: 228 Year : 1999 Posts: 43 Status: Offline posted         The 99 manual calls for 87-101 ft lbs for the 2 nuts under each shock tower and 69-86 ft lbs for each bolt into the frame and crossbar. -------------------- Ken Jim Venable Member Region: NW Year : 90 Posts: 54 Status: Offline posted         Thank you Ken.

I'll check my '95 Workshop Manual and let you know. -------------------- Rob Gibson RJ Racing 2010 NASA Nationals TTE Champion 2008/2009 WERC Champion 2007 NASA SoCal SM Champion rjracing.net Weekend-Racer.com Jim Venable Member Region: NW Year : 90 Posts: 54 Status: Offline posted         Rob, That would be appreciated as I'm about to take the car off the jackstands for the first time. Everytime I've been under it my eyes gander a questioning look at the subframe nuts and bolts. Jim "Nice Guy Jim Racing" Gibscreen Member Region: NASA-SoCal Car #: 23 Year : 1995 Posts: 912 Status: Offline posted            I'm showing 69-86 ft-lb for the nuts under the shock towers, and 51-61 for the rear subframe bolts. The only bolts that I see that are 87-101 ft-lb are the upper control arm bolts. Below are links to the torque spec pages from the 1995 Workshop Manual (the 3rd set of numbers are ft-lb). Front Subframe Rear Subframe I'm not sure if Ken and I are just using different terminology, so you can see for yourself what I'm talking about. -------------------- Rob Gibson RJ Racing 2010 NASA Nationals TTE Champion 2008/2009 WERC Champion 2007 NASA SoCal SM Champion rjracing.net Weekend-Racer.com Jim Venable Member Region: NW Year : 90 Posts: 54 Status: Offline posted         Thank you fellas. Considering I have an early model I think it would be best to back the torque off a hair or two for some of the nuts and bolts just to be safe. Be well, Jim Gibscreen Member Region: NASA-SoCal Car #: 23 Year : 1995 Posts: 912 Status: Offline posted            Whenever I'm torquing fasteners, I always think of the late, great Carroll Smith who said to always err on the side of undertightening. He rarely saw part failures from undertightening, but he's seen countless failures from overtightening. -------------------- Rob Gibson RJ Racing 2010 NASA Nationals TTE Champion 2008/2009 WERC Champion 2007 NASA SoCal SM Champion rjracing.net Weekend-Racer.com Printer-friendly view of this topic | Subscribe To Topic Hop To: Select a Forum:   Category: SpecMiata.com -------------------- Spec Miata Spec Miata Garage Spec Miata Rules & Competition Spec Miata Competition Tires Spec Miata Safety Spec Miata Setup Guide Spec Miata Data Acquisition NASA PTE/E3 Spec Miata to FProd SMulators Spec Miata Frequently Asked Questions Showroom Spec Miata Pro Miata Spec Miata Enduro Spec Miata Virtual Swap Meet SMTV Back Fire Announcements   Category: Spec Miata Archives -------------------- Spec Miata 2001-2009 Garage 2002-2009   Category: Sports Car Club of America -------------------- SCCA North-East SCCA South-East SCCA Great Lakes SCCA Central SCCA Mid-West SCCA South-West SCCA Rocky Mountain SCCA North Pacific SCCA San Francisco Region SCCA South Pacific   Category: National Auto Sport Association -------------------- NASA Discussion NASA Northeast NASA Southeast NASA Central NASA Midwest NASA Northwest NASA Southwest   Category: Mid Western Council -------------------- MWC Discussion
